Big Pop,
I am not sure on this but I mentioned pulling the carburetor top and actually seeing if the bowl was full, as opposed to looking down the throat while working the throttle because I think the accelerator pump will squirt fuel with
a less than full (almost empty) bowl!
Usually, in the case of plugged jet, it will either be an idle jet, which allows the rig to run high rpm's only or a high speed jet which would allow the
engine to idle but not attain high speed. Does your engine NOT do either of these things?
